    Without any argument, this function clears the current window.
    Otherwise it clears the graphics windows whose numbers are included 
    in the vector <tt>
        <b>window-id</b>
      </tt>. For example <tt>
        <b>xclear(1:3)</b>
      </tt> clears windows
    1, 2 and 3.
    If one of the windows does not 
    exist, then it is automatically created.</p>
    <p>
    Warning: in recording mode <tt>
        <b>xclear</b>
      </tt> clears
    the window, but it does not erase the recorded commands.
    In this case you must use the function <tt>
        <b>xbasc</b>
      </tt>.</p>
